The JW Marriott Orlando Grande Lakes is near SeaWorld at 4040 Central Florida Parkway, Orlando, FL. Visible along the horizon for miles in either direction from John Young Parkway this recognizable landmark is one of the finer place to stay while in Orlando.
Located in the opposite direction that most of the crowd will go when SeaWorld closes and a short drive, only 2 miles from the entrance of SeaWorld Parking (just stay on Central Florida Parkway).
That means that the I-Ride Trolley does not go by or even near this hotel. Neither does Lynx. So, public transportation does not treat the people that stay at this hotel with great respect!
So, a rental car, or your own car is almost a necessity if this is your accommodations while in Orlando. Why not use some of those free rental car miles to explore other things to do in Florida (like Kennedy Space Center, Lakeridge Winery & Vineyards or Daytona International Speedway)?
Maybe even discover which of the two Narcoossee's (it means "bear" or "little bear" depending upon which interpreter you believe) you like better.
However, driving to the major attractions is really easy from this hotel.
